In EM systems, there can be various contaminations: The contamination spots on specimens provide some useful applications, for instance: Modern AEMs (analytical electron microscopes) have relatively clean vacuum systems, with residual hydrocarbons in the specimen region being <10-10 torr. However, it is still possible to build up hydrocarbon (HC) and carbon (C) contaminants on the specimens. In general, there are many drawbacks induced by the contamination on specimens, for instance: |
